ACM InterCHI 1993 Isssue 88 - Browsing Graphs Using a Fisheye View

The video demonstrates a system for viewing large graphs. It's one of many possible implementations of a general framework for graphical fisheye views that we have developed. The graphin the video represent direct routes between major cities in the US. An obvious way to see more detail about an area is to zoom into the graph. However; as the user zooms into an area; less of the graph is visible so the global structure of the graph is lost. This becomes more acute as the user pans the zoomed image.
